SPECIFICATION forming part of Letters Patent No. 679,423, dated July 30, 1901. Application filed January 21, 1901. Serial No. 44,031. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES E. House, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented new and useful Improvements in Head-Rests, of which the following is a specification.

My invention relates to improvements in head-rests for surgical and dental chairs; and it consists in providing means by which a head-rest may be adjusted upward and downward in front of the back of a chair and locked in any desired position, as will be hereinafter more fully described and claimed.

In the accompanying drawings, similar letters of reference refer to similar parts.

Figure l is a perspective view of the back of a chair with my invention applied thereto. Fig. 2 is a perspective view from the back of a chair. cushion and head-rest, showing the method of engaging the towel therewith. Fig. 4 is a perspective view of the retaining-band by means of which the towel is held in engagement with the cushion. Fig. 5 is a perspective view of aportion of the head-rest bracket. Fig. 6 is a perspective view of the cam-lock. Fig. 7 is an interior side view of the bracket, showing the method of engagement with the ways or straps.

To the back of the chair A, I attach upon either side thereof the metal ways a a, made of ordinary strap-iron, along which the brackets B and B are adapted to slide in their upward and downward movement. The brackets B and B are provided with the projecting flanges b and b, which form a bearing for and slide upon the guides or ways a a. The flange b is curved outward at its center, and has a forwardlyprojecting lug 19 which serves as a lock against the cam 5 which is mounted in the bracket and journaled upon the rod 6 which connects the brackets together. The cam-block b is provided upon one side with a depression 6 which serves in conjunction with the forwardly-projecting lug b of the bracket as a lock to prevent the cam from passing the center. The cams are adapted to be operated simultaneously by means of the handle I), keyed or pinned to the bar I). The forward portion of the bracket may be of any desired form or ornamenta- Fig. 3 is a perspective view of thetion, so that it projects forward and terminates in the arms to'which is attached the cushion D. The head-cushion D consists of a rigid support (Z, extending from bracket to bracket, and having mounted thereon upon either side and spaced apart padded cushions cl and (Z For the purpose of keeping the head-cushion fresh and clean I have provided the retaining-band E, which consists of a metallic band, conforming in shape to the rest D, and after the towel has been placed over the rest the retaining'band is slipped over the same, and the towel is securely held in engagement and may be readily detached for the purpose of renewing the same.

In operation the head-rest can be moved up and down along the front of the back of a chair and adjusted at any desired position by means of the operating lever or handle at the back of the chair, the movement of which engages or disengages the cam-blocks from the guides or ways at the will of the operator, or, if desired, the head-rest can be entirely removed from the chair. It is especially desirable that a head rest be capable of these adjustments that it may be adapted to the different sizes of people on the operatingchair, or, as is frequently the case, if it is desired to form a support for the back, side, or abdomen of a patient to make more promi" nent the part of the bodyto be operated upon.

Various changes in construction and configuration may be made without departing from the spirit of my invention, which consists, primarily,in providing a head-rest capable of an upward and downward movement along and across the front of the back of a chair.

Having thus fully described my invention, what I desire to secure and claim by Letters Patent is-- 1. The combination in a head-rest for surgical and dental chairs, of ways attached to the back of the chair, brackets engaging therewith and projecting forwardly of the back of the chair, a head-support engaging the brackets, and means for locking the brackets in engagement with the guides or ways, substantially as described and for the purpose set forth.

2. The combination in a head-rest for surgical chairs, of ways attached to the back of the chair, brackets mounted thereon and excushion-support attached to the forward ends of the-brackets, a coupling-rod journaled in the brackets, and cam-locks mounted thereon, substantially as described and for the purpose set forth.

3. The combination in a head-rest for surgical chairs, of ways attached to the back of the chair, brackets mounted thereon and extending forwardly of the back of a chair, a cushion-support engaging the forward ends of the brackets, cam-locks mounted in the brackets, a coupling-rod journaled therein, and a retaining-band conforming to, and adapted to engage with, the cushion-support, substantially as described and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses. v

CHARLES E. HOUSE.
